CVE-2025-48261: CWE-201 Insertion of Sensitive Information Into Sent Data in MultiVendorX MultiVendorX
Insertion of Sensitive Information Into Sent Data vulnerability in MultiVendorX MultiVendorX allows Retrieve Embedded Sensitive Data. This issue affects MultiVendorX: from n/a through 4.2.22.
AI Analysis
Technical Summary
CVE-2025-48261 is a high-severity vulnerability classified under CWE-201, which involves the insertion of sensitive information into sent data within the MultiVendorX product. MultiVendorX is a multi-vendor marketplace platform, and this vulnerability affects versions up to 4.2.22. The core issue is that sensitive information is embedded into data transmitted by the application, which can be retrieved by an attacker without any authentication or user interaction. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the vulnerability can be exploited remotely over the network with low attack complexity, no privileges required, and no user interaction needed. The impact is primarily on confidentiality, as attackers can retrieve sensitive data embedded in the sent data streams, potentially exposing private or confidential information. There is no indication that the vulnerability affects integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that remediation may still be pending or in development. The vulnerability was reserved in May 2025 and published in June 2025, indicating it is a recent discovery.
Potential Impact
For European organizations using MultiVendorX as their e-commerce or marketplace platform, this vulnerability poses a significant risk to the confidentiality of sensitive business and customer data. Exposure of embedded sensitive information could lead to data breaches involving customer personal data, payment details, or proprietary business information. This can result in regulatory non-compliance, especially under GDPR, which mandates strict controls over personal data protection and breach notification. The loss of confidentiality could damage customer trust, lead to financial penalties, and harm the organization's reputation. Since the vulnerability does not require authentication or user interaction, attackers can exploit it remotely and at scale, increasing the risk of widespread data leakage. The lack of current known exploits provides a small window for mitigation before active exploitation begins, but organizations should act promptly to assess exposure and implement controls.
Mitigation Recommendations
European organizations should immediately conduct a thorough audit of their MultiVendorX installations to identify affected versions (up to 4.2.22). Since no official patches are currently linked, organizations should engage with the vendor or community for updates or interim fixes. In the meantime, network-level controls such as restricting external access to the MultiVendorX application, implementing strict firewall rules, and deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious data exfiltration attempts are recommended. Additionally, organizations should review and minimize the amount of sensitive information embedded in data transmissions wherever possible, applying data masking or encryption techniques. Monitoring network traffic for unusual patterns and setting up alerting for potential data leakage attempts can help detect exploitation attempts early. Finally, organizations should prepare incident response plans specific to data leakage scenarios and ensure compliance with GDPR breach notification requirements.
